Barbara Mikulski has the best approval numbers of any Senator we've looked at in the last ten months other than John Thune. Add to that a slate of opponents who are about as anonymous as any Senate candidates in the country and it adds up to a wide lead for Mikulski as she bids for reelection.
54% of voters in the state approve of the job Mikulski's doing to 32% who disapprove. 76% of Democrats give her good marks and independents break down favorably by a 41/32 margin as well. Mikulski doesn't have much crossover support- only 14% of Republicans think she's doing a good job.
Just 18% of voters in the state claim to know enough about James Rutledge to have an opinion one way or the other and only 10% have one about Eric Wargotz. Rutledge's favorability breaks down 5% positive and 13% negative, and Wargotz's is only 1% positive and 9% negative. Those unfavorable numbers for Rutledge and Wargotz are probably a reflection of voters who just say they dislike all politicians, rather than true enmity toward the little known candidates themselves.
Mikulski leads Rutledge 58-30 in a hypothetical contest and holds an even wider 59-27 advantage over Wargotz.
A lot of Democratic incumbents who looked pretty safe a year ago have become vulnerable with the passage of time, but it looks pretty unlikely that's going to be the case with Mikulski.
